RPG's?

Is there any good RPG doom/hexen/heretic mods? And which ones will work for mac? I have 2 versions of Zdoom and I really would like to try a RPG themed one.
If so, how would i get it to work? Thank you :)

Community is Falling series has RPG type elements in it.

Serpent: Resurrection.

Serpent won't work because it requires GZdoom and GZdoom won't work on mac :/

try Strife: Quest for the Sigil (Doom-engine game) or if you have a mobile phone, Doom RPG

rtc-3057: system shock-y

a furry tale: lilwhitemouse's...yeah, it has furries, but it also has a nice little adventure, shops, and random battles.

phocas island 2: an item-centric adventure game in doom.

that's all i can think of at the moment sir.

Do those let you level up or something similar?
